^Cstrace: Process 1077 detached感谢大佬的回复，一直持续输出这东西看情况是好像是业务上某个定时任务，好像一直循环操作redis，我应该知道问题所在了，请问大佬这个可以排查到具体代码吗？虽然这个输入也可以排查但是用到相同的key很多，排查起来比较慢。

看起来Swoole\Crorutine\Socket::recvAll()每次只使用一个长度为1的缓冲区去获取数据，每次就获取1字节的数据

类似的问题，可以使用 strace、gdb（zbacktrace）、perf 等工具进行跟踪调试
php-src 和 swoole-src 提供的 gdbinit 脚本，里面有很多工具可以查看相关的信息
